Econometrics Help
 

I'm having problems with #5. I took the partial derivative of the error term with respect to beta-1 and set that equal to 0, but have no idea where to go from there. Right now I have E(XiYi) - E(XiB0 + Xi^2B1) = 0 where E is sigma and B is beta.

[x] Reminded me why I quit Econ

I'd write down marginal cost, stagflation, or some other economics buzzword.

I think I would get some sleep before tackling anything too challenging; you're just making up words now.

God I hated Econometrics. Our final was a single proof that took like 8 pages. Unfortunately for you, I immediately forgot everything I learned. Sorry

It's sad that I used to be able to do this...then I went to law school and forgot everything about it. I loved econometrics though.

Re: Econometrics Help
 

an econ prof once said to my class " econ is the major for the kids who can't do math, and politics is the major for the kids who can't do econ." Anyways, I'm an econ major and I've taken econometrics and i suggest poker as an alternative.

Re: Econometrics Help
 

i would've covered up the prof's name in that print screen, you might get evenkeal'ed

Re: Econometrics Help
 

[x] got degree in economics
[x] took and passed econometrics class
[x] have t-shirt commemorating passing econ class
[ ] can come close to answering or even understanding anything about question

Yes

Re: Econometrics Help
 

I was a gov major but beta nought should equal:

Y bar - ( (E (Yi-Ybar)*(Xi-Xbar))/(E (Xi-Xbar)^2) * (Xbar i)

Sounds like the prof is getting fancy using "derived." You don't need to find a derivative to answer the questions correctly.

To show the proof you do.

Re: Econometrics Help
 

Any basic statistics/econometrics textbook would have the derivation for this. Your uni library would have tons of them.
